Be it known that I, JOHN A. SAMPLE, a citizen of the United States,residing at Rankin, in the county of Allegheny and State of Penn-Sylvania, have invented certain new and usefnl Improvements in-Draw-Barsfor Railway- Cars; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains t make and use the same,reference being had to the ac companying drawings, which form a part ofthis specification. y

My invention relates to an improved drawbar for railway cars, and itconsists incertain details of construction, and combination of parts aswill be fully described hereinafter.

In the accompanying drawings, Figure l is a plan view of my improveddraw head, having the draw-bars broken from the head at the other end ofthe car. Fig. 2 is a sectional side elevation of the same. Fig. 3 is atrans- Yverse sectional elevation taken on the line To put my inventioninto practice I provide a casting or frame l and attach the same beneaththe floor of a railway car at the rear of the position occupied by theordinary draw head. This frame is provided with openings 6 at each side,and inwardly projecting portions 2 which serve as guides for the drawhead 4 arranged within the frame. Thisl draw head consists in a casting4 having a head 5 for the reception of the coupling link. Formed in thedraw head 4: is an opening extending in the direction of the length ofthe same and engaging with the inwardly projecting porvward but alimited distance.

tions 2. Operating within this draw head is a shaft 9 attached to across, piece 7, and extending rearward through the said draw head, andthrough the rear of the frame, and having two intermediate springs 10,and 1l. A key l2 passed through one endof the shaft serves to preventthe same from working foro Attached to each end of the cross piece 7 aredraw bars 13, which extend rearward and are connected to a draw head ofa similar construction, as that above described.

These draw bars constructed as described. and arranged inpositionbeneath the oor of a railway car, will remove all strain from the car.
